Geräte Informationen:

The 3586A/B Selective Level Meter is designed for use in the design, manufacture, installation, and maintenance of Frequency Division Multiplex (FDM) systems and for general purpose wave analysis and frequency synthesis. The 3586A is available to meet the needs of C.C.I.T.T. requirements, while the 3586B meets North American (Bell) Standards. The 3586C is a general purpose instrument.
The 3586A/B provides the ability to make both carrier frequency measurements to 32.5MHz and voice channel measurements from 50Hz to 100kHz.
The Transmission impairments Option 003 allows the user to quickly troubleshoot voice channel problems with phase jitter, noise-with-tone, signal-to-noise-with-tone-ratio, and single level impulse noise measurements, all with one instrument. The capability to make all these transmission impairment measurements combined with both FDM voice channel and carrier frequency measurements is available only on the 3586A/B. Standard models include a 1740Hz psophometric or 2000Hz C-message equivalent noise filter, or weighted noise measurements can be made directly with the 3100Hz channel filter and noise weighting filter provided with the Transmission Impairments Option 003. Filter shape factor of < 1.2 provides 60dB carrier and 75dB adjacent channel rejection.

This manual applies to all instruments. Earlier versions of
the 3586A/B/C, however, may differ in design and appearance
from the instruments this revision documents directly.
Changes that have been made to the instrument and which
affect the instrument's documentation are identified by the
delta (A) symbol. The "numbered" A refers the reader to the
corresponding numbered A in the backdating section (Section
VII) in Volume I of the 3586A/B/C Service Manual.

8-2. This volume of the Service Manual contains information
relative to the maintenance and service of the 3586A/B/C
Selective Level Meter. The information presented in this
manual is assembled into four major segments: Turn-on
Initialization and Milking the Front Panel, Troubleshooting,
Detailed Functional (circuit) Description, and Service
Groups. Where references are made throughout the manual to a
performance test, adjustment procedure, the parts list, or
backdating section, refer to Volume I: 3586 Performance
Tests, Adjustments, Parts, and Backdating. In order to
obtain a minimum of instrument down time and to provide for
the greatest amount of troubleshooting efficiency and
safety, it is recommended that Safety Considerations
(paragraph 8-5), Use Of The Service Manual (paragraph 8-8),
and Service Volume Organization (paragraph 8-11) be read
before initiating any troubleshooting procedures.
